Class NodeMappingStats

java.lang.Object

org.elasticsearch.index.mapper.NodeMappingStats

All Implemented Interfaces:

Writeable, ToXContent, ToXContentFragment

public class NodeMappingStats
extends Object
implements Writeable, ToXContentFragment

Node stats for mappings, useful for estimating the overhead of MappingLookup on data nodes. Should be used at node or index level, and not at shard level, since the mappings may be shared across the shards of an index.
